PADDING FOR SEAT BACKS.

Original application filed December 26, 1923. Serial No. 682,839. Patent No. 1,650,086, dated November 22, 1927. Divided and this application filed October 19, 1925. Serial No. 63,292.

The presentinvention relates to improvements in padding for backs of auton'iobile seats, or similar upholstery, and the particular object of the invention is to provide a padding that will completely fill an elongated pocket provided for its reception and press the some into cylindrical form, which is particularly adapted to resist wear and to maintain its resiliency for a long period m of time.

It is further proposed to arrange the padding as an individual article and to use for this purpose two ditferent kinds of materials, the outer shell or sleeve being made of material of considerable tensile strength, such as long staple cotton, and an inner fil ing of low. tensile strength, such as short lengths of ute, waste cotton, and other short fibre material. It is proposed to use the filler for forcing the sleeve int-o cylindrical form, and to also provide a stiffening element which is used to longitudinally reinforce the padding so as to facilitate its introduction into a pocket and to oppose bending stresses.

The present application is divisional to application, Serial No. 682,839, filing date, Dec. 26, 1923, Patent No. 1,650,086, Nov. 22, 1927, and the device described herein is one of the forms originally presented in the latter application.

The form desired to be protected in this application is illustrated in the accompanying drawing, in which:

Figure 1 shows a perspective view of a padding, and

Figure 2 a transverse section through the same.

llfy device, as illustrated in Figures 1 and 2. comprises a sheet 1 of flexible material made of considerable tensile strength, and preferably consisting of long fibre cotton, and rolled or coiled into a sleeve with the two ends of the sheet overlapping as shown at 2, these two ends being preferably glued together by means of an adhesive.

A. tiller 3 made preferably of inferior, or waste material, such as waste cotton, jute, or other short fibre material, is crowded into the flexible sleeve so as to press the same into the cylindrical form shown in the draw ing. A reinforcing strip 4 of paper, or any other suitable material, is introduced inside of the sleeve, and preferably in the center thereof, and extends throughout the length of the padding. It may be coated with an adhesive so as to cause the filling material to stick thereto. lined to one face of the stiffening strip.

1 claim: 1. A padding material made for endwise introduction into an elongated pocket and comprisinga sleeve made of flexible material of considerable tensile strength, a filler of comparatively short fibre pressed into the sleeve so as to force the latter into cyliiulrical form and a stiffening member xvi. the sleeve extending lengthwise thereof, said stiffening member to be spaced from said sleeve.

A padding material made for cndwise introduction into an elongated pocket and emnprising a sheet of flexible material of considerable tensile strength coiled to form a sleeve with overlapping edges, :1 filler of comparatively short fibre pressed into the sleeve so as to force the latter into cylin drical form and a stiffening member within the sleeve extending lengthwise thereofand being spaced from said sleeve.

3. A padding material made for cndwise introduction into an elongated pocket and comprising a sleeve. made of flexible material of considerable tensile strength, a filler of comparatively short fibre pressed into the sleeve so as to force the latterlinto cylindrical form, and a stiffening centrally within the sleeve and extending lengthwise thereof and spaced therefronn 4i. A padding material made for endwise .itroduction into an elongated pocket and comprising a sleeve, made of flexible material of considerable tensile strength, a filler of comparatively short fibre pressed into the sleeve so as to force the latter into cylindrical form, and a stiffening centrally within the sleeve and extending lengthwise thereof, and spaced therefrom having an adhesive on at least one face thereof. 7
